Preventing suicidal behaviour amongst adolsecents: hospital admissions as a behavioural measure in analysing the effectiveness of a school-based programme.

Masters Degree. University of KwaZulu-Natal, Pietermaritzburg.This study aimed to develop, implement and analyse the effectiveness of a school-based prevention programme aimed at reducing the high rate of parasuicide amongst Indian adolescents in Pietermaritzburg, Natal. This thesis is concerned with long-term effects of the programme, specifically whether the intervention would lead to a decrease in parasuicide amongst Indian adolescents in this region. Schools were randomly divided into an intervention · and control group, and parasuicide hospital admissions from a local hospital were examined to determine pre-intervention and post-intervention parasuicide admission rates. Data analysis attempted to take seasonal fluctuations into account, and both the T-tests for mean differences and Regression Analyses revealed that in the postintervention period there was a significant decline in parasuicide admissions for all adolescents. Furthermore an examination of the data indicates that in the postintervention period adolescents from the experimental group had significantly lower hospital admission rates than adolescents from the comparison group. Gender differences revealed that female adolescents benefitted more from the programme than \ male adolescents. These results are discussed with possible explanations and recommendations for future research.Quality of scanned PDF has been compromised owing to poor condition of original document.

Instrumentation for Measurement of Gas Permeability of Polymeric Membranes

A mass spectrometric 'Dynamic Delta' method for the measurement of gas permeability of polymeric membranes has been developed. The method is universally applicable for measurement of the permeability of any gas through polymeric membrane materials. The usual large sample size of more than 100 square centimeters required for other methods is not necessary for this new method which requires a size less than one square centimeter. The new method should fulfill requirements and find applicability for industrial materials such as food packaging, contact lenses and other commercial materials where gas permeability or permselectivity properties are important

Development of a New Data Tool for Computing Launch and Landing Availability with Respect to Surface Weather

The Marshall Space Flight Center Natural Environments Branch has a long history of expertise in the modeling and computation of statistical launch availabilities with respect to weather conditions. Their existing data analysis product, the Atmospheric Parametric Risk Assessment (APRA) tool, computes launch availability given an input set of vehicle hardware and/or operational weather constraints by calculating the climatological probability of exceeding the specified constraint limits, APRA has been used extensively to provide the Space Shuttle program the ability to estimate impacts that various proposed design modifications would have to overall launch availability. The model accounts for both seasonal and diurnal variability at a single geographic location and provides output probabilities for a single arbitrary launch attempt. Recently, the Shuttle program has shown interest in having additional capabilities added to the APRA model, including analysis of humidity parameters, inclusion of landing site weather to produce landing availability, and concurrent analysis of multiple sites, to assist in operational landing site selection. In addition, the Constellation program has also expressed interest in the APRA tool, and has requested several additional capabilities to address some Constellation-specific issues, both in the specification and verification of design requirements and in the development of operations concepts. The combined scope of the requested capability enhancements suggests an evolution of the model beyond a simple revision process. Development has begun for a new data analysis tool that will satisfy the requests of both programs. This new tool, Probabilities of Atmospheric Conditions and Environmental Risk (PACER), will provide greater flexibility and significantly enhanced functionality compared to the currently existing tool

Achieving the Promise of Educational Opportunity: Graduate Student Debt for STEM vs. Non-STEM Students, 2012

Using NPSAS 2012 data, this study examines graduate student debt for STEM versus non-STEM students who were enrolled in a master’s or doctoral degree program in 2012. Findings showed significantly higher debt for those in non-STEM programs as well as differences by amount of undergraduate debt, race, and full- or part-time enrollment status. These differences may encourage more STEM participation, but may restrict some students from enrolling in graduate-level programs, particularly in non-STEM fields. The loss of a new generation of citizens with graduate level training may affect our national economy and productivity, and urges institution officials to consider means to offer financial aid to a larger number of graduate students

Surface Landing Site Weather Analysis for NASA's Constellation Program

Weather information is an important asset for NASA's Constellation Program in developing the next generation space transportation system to fly to the International Space Station, the Moon and, eventually, to Mars. Weather conditions can affect vehicle safety and performance during multiple mission phases ranging from pre-launch ground processing of the Ares vehicles to landing and recovery operations, including all potential abort scenarios. Meteorological analysis is art important contributor, not only to the development and verification of system design requirements but also to mission planning and active ground operations. Of particular interest are the surface weather conditions at both nominal and abort landing sites for the manned Orion capsule. Weather parameters such as wind, rain, and fog all play critical roles in the safe landing of the vehicle and subsequent crew and vehicle recovery. The Marshall Space Flight Center (MSFC) Natural Environments Branch has been tasked by the Constellation Program with defining the natural environments at potential landing zones. This paper wiI1 describe the methodology used for data collection and quality control, detail the types of analyses performed, and provide a sample of the results that cab be obtained

An investigation of microstructural characteristics of contact-lens polymers

The free volume and gas permeability in several contact lens specimens were measured as part of a Space Commercialization Program. Free volume was measured using positron lifetime spectroscopy, while permeability for O2, N2, CO2 gases was measured using mass spectrometry and polarography. Permeability for all gases increases with the mean free volume cell size in the test samples. As might be expected, the specimens with the highest free volume fraction also exhibit the lowest Rockwell Hardness Number. An interesting corollary is the finding that the presence of fluorine atoms in the lens chemical structure inhibits filling up of their free volume cells. This is expected to allow the lenses to breathe freely while in actual use

Identifying invertebrate invasions using morphological and molecular analyses: North American Daphnia ‘pulex’ in New Zealand fresh waters

We used a DNA barcoding approach to identify specimens of the Daphnia pulex complex occurring in New Zealand lakes, documenting the establishment of non-indigenous North American Daphnia 'pulex'. Morphological delineation of species in this complex is problematic due to a lack of good morphological traits to distinguish the species, as there is a relatively high degree of morphological stasis within the group through evolutionary time. Accordingly, genetic analyses were used to determine the specific identity and likely geographic origin of this species. Morphologically, individuals most closely resembled Daphnia pulicaria or Daphnia pulex sensu lato, which cannot be separated morphologically. Furthermore, each of these taxa comprises separate species in North America and Europe, despite carrying the same names. We identified individuals using a 658 bp nucleotide portion of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) as North American Daphnia 'pulex', being distinct from European Daphnia pulex sensu stricto and D. pulicaria from Europe or North America. Cellulose allozyme electrophoresis was used to confirm that individuals were not hybrids with D. pulicaria. North American Daphnia 'pulex' in New Zealand were first recorded in New Zealand from South Island lakes that are popular for overseas recreational fishers, indicating a possible source of introduction for this species (e.g. on/in fishing gear). Our study provides an additional example of how genetic techniques can be used for the accurate identification of non-indigenous taxa, particularly when morphological species determination is not possible. The growth of global databases such as GenBank and Barcode of Life Datasystems (BOLD) will further enhance this identification capacity

Design strategies for mitigating passenger door holding behavior on suburban trains in Paris

The length of time a train is halted at a station is particularly important during service peak periods and short headways. Some passenger behaviors, such as the deliberate holding open of doors, has a detrimental effect upon maintaining short dwell times and service timetable. Mechanical malfunction due to door holding is also a significant contributor to trains having to be removed from service.There is a general absence of literature in the transportation field examining this problem or offering potential solutions. This paper discusses a commissioned research project carried out by Monash University’s Department of Design for the French National Railway (SNCF). The method for this research drew upon techniques from other related disciplines to aid in the formulation of a design strategy to mitigate passenger door holding behavior.Leveraging the physical design of the environment to provoke desired behaviors in people is a technique widely used in various disciplines from large architectural projects to more subtle uses of applied psychology. This paper describes the background to the problem as it manifests itself on SNCF’s network in the Ile-de-France and discusses potential design solutions that may have pertinence for other networks similarly afflicted around the world

Mapping the (Invisible) Salaried Woman Architect: the Australian Parlour Research Project

Since the 1970s, feminist historians and polemicists have struggled to uncover the ordinary lives of women. They believe that gender ideals and biases are a critical part of the weft and weave of daily life. But the quotidian has been a restricted field in our discipline, often used to define a particular building type rather than the lives of architects. For example, we know little about the workdays of professionals or their labour in the workplace. The architectural office - its daily transactions and everyday culture - remains obscure. Even when represented in histories of the profession, the architectural office is filtered through a top-down lens trained on practice directors. The labour and lives of architecture’s male and female employees is unexplored terrain, but we could begin with the demographics: up to three-quarters of Australian women in architecture are salaried workers, continuing a historical trend. In the past, women generally worked for others. The gendering of salaried architectural workers raises questions about the relationship between gender and office work. Feminist historians and theorists have suggested that the office plays a role in forming gender ideals and practices. This paper endeavours to critically describe the lives and labour of women architects at the office, using survey and interview data from a large-scale Australian research project, publicly known through its website Parlour. This research inquires into gender disadvantage and investigates how gender ideals and norms shape the culture of the architectural workplace. The project’s research questions, evidence and explanations form the basis of this essay. The Parlour project is an ongoing platform for sharing information and research, but it gives particular voice to women’s experience in architecture, an experience largely shaped by salaried employment, studentship and the ownership of small practices

Reducing variation not function: Lessons from applied route bus design research

Individual bus operators specify vehicles in line with their own unique requirements. Collectively, diversity across vehicle specifications increases costs and lead time and decreases quality in local bus manufacture, paradoxically having negative consequences for the very function that specifications were intended to improve. The vehicle specifications are driven by functional requirements and are therefore difficult to reconcile with manufacturing by simply reducing them. This research set out to develop bus designs balancing user and manufacturer needs.Investigation found that specification diversity results from bus operators determining designs to meet their requirements – resulting in a raft of solutions to the same or similar problems. Two interventions to this situation were formulated; that a higher-specification product could offer equal or better function to bus operators while being of standardised manufacture; and that a system of modular design could be implemented where specification differences were functionally justified.These approaches were tested in the design, manufacture and implementation of a new driver’s area for route buses. It was found to meet the functional requirements of several Australian bus operators while streamlining manufacture. It resulted in a definitive design strategy for the development of better public transport vehicles
